Title: Adaptive array antenna reception apparatus and antenna array calibration method
Inventor: HASEGAWA YASUHIRO
IPC: H04B7/08
Filed: 2002-04-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide an adaptive array antenna reception apparatus for performing accurate directivity control by compensating for an amplitude/phase characteristic difference even if an input power level to an electronic element changes.  <P>SOLUTION: A probe signal generation section 101 generates a probe signal that has the same frequency as a communication traffic signal. Probe signal synthesis sections 103-1 to 103-n synthesize communication traffic signals and the probe signals that are received by antennas 102-1 to 102-n. The synthesized signals are frequency- converted to become reception baseband signals. An amplitude/phase information acquisition section 105 extracts the probe signals from the reception baseband signals, and acquires amplitude/phase information from the probe signals. A reception power measurement section 106 measures the reception power of the reception baseband signals. A calibration value control section 107 adaptively determines a calibration value based on the amplitude/phase information and the reception power. A characteristic difference compensation section 108 compensates for the amplitude/phase characteristic difference of the reception baseband signals for each antenna using the calibration value.  <P>COPYRIGHT: (C)2004,JPO
